This recipe calls for common ingredients that you may have in your kitchen already. You will find the exact amounts on the recipe card below.

How to Make Lunch Lady Peanut Butter Bars

Prep time for these rich treats is only 15 minutes. As long as you can wait for them to firm up in the fridge for at least 1 hour, it takes such little time!

  • Prepare a Baking Dish. You will need to line an 8×8 baking dish with aluminum foil. Make sure there is some extra hanging over the sides for easy removal. Parchment paper will also work great.
  • Make the First Layer. In a large microwave-safe bowl, melt the butter. Mix the melted butter with the powdered sugar, graham cracker crumbs, and peanut butter. Make sure it is well combined and smooth.
  • Add to the Dish. Pour the peanut butter mixture into the bottom of the lined baking dish. Spread it evenly with a spatula.
  • Prepare Chocolate. Melt the chocolate chips in 30-second intervals in the microwave, stirring each time until smooth. Use a medium microwave-safe bowl for this step.
  • Add to the First Layer. Pour the melted chocolate over the top of the peanut butter mixture and spread evenly.
  • Chill. Place in the refrigerator for 1 hour to firm up.
  • Serve. Slice into 16 equal bars and enjoy!

How to Store Leftovers

Store leftovers in an airtight container in the refrigerator for up to 4 days. I do not recommend leaving them at room temperature. They will become soft and start to melt.

Can I Freeze This?

You can absolutely freeze these peanut butter bars! I recommend cutting them beforehand so they can be frozen individually. This makes it easier to thaw. They will last in the freezer for 2-3 months.
